Abstract
A first wellbore includes a substantially horizontal or inclined portion in a hydrocarbon containing layer in the formation. A first conductor having electrically conductive material is at least partially positioned in the first wellbore. At least one conducting material substantially surrounds the first conductor in the first wellbore. A second conductor having a substantially horizontal or inclined portion is located in the hydrocarbon containing layer in the formation. The second conductor includes electrically conductive material. At least one conducting material substantially surrounds the second conductor. A power supply is coupled to the first conductor to electrically excite the electrically conductive materials of the first conductor such that current flows between the electrically conductive materials in the first conductor, through at least a portion of the formation, to the second conductor, and the current resistively heats at least a portion of the formation between the two conductors.
